How it works (the boring stuff):The distance is calculated using the spherical law of cosines. The formula is cos c = cos a cos b + sin a sin b cos C).
The bearing that points to your direction is calculated using the great circle path (orthodrome). This shows you the direction to your target waypoint ‘as the crow flies’. The formula is θ = atan2( sin Δλ ⋅ cos φ2 , cos φ1 ⋅ sin φ2 − sin φ1 ⋅ cos φ2 ⋅ cos Δλ )
Navigation made easy. Just tag your location and be assured wherever you go, you’ll always be able to find your way back. Explorers Wanted!
